Figure 4: Hydrographic conditions over sampling period. Average salinity, dissolved oxygen, water 

 temperature, and turbidity measured each sampling date. Standard error bars are smaller than symbols. 

 Minor ticks placed every Monday. Daily rain fall and inflow from gage (USGS 1997). 



Figure 5: Average flow velocity measurements from flow treatments on two dates (7 May and 

 17 July 1997). Tukey minimum significant difference is 26.45 for flow regimes, and 18.29 for dates.
